Frequently asked questions (FAQ) about color printing

What is RGB color?

Red, green, and b lue light c an be added together in various amounts to produce a large range of colors observed
in nature. For example, red and green light can be combined to create yellow light. Televisions and computer
monitors create colors in thi s manner. RGB color is a method of describing color s by indicating the amount of red,
green, and blue light needed to reproduce a particular color.

What is CMYK color?

Cyan, magenta, yellow, and black inks or toners can be printed in various amounts to produce a large range of
colors observed in nature. For example, cyan and yellow can be combined to create green. Printing presses,
inkjet printers, and col or laser printers create co lors in t his manner. CMYK color is a method of describing colors
by indicating the amount of cyan, magenta, yellow, and black needed to reproduce a particular color.

How is color specified in a document to be printed?

Software applicati ons typically specify document color us ing RGB or CMYK color combinations. Additionally , t hey
commonly let users modify the color of each object in a document. Since the procedures to modify colors vary
depending on the application, see the software application Help section for instruction.

How does the printer know what color to print?

When a user prints a document, information describing the type and color of each object in the document is sent
to the printer. The co lor information is passed through color conversion tab les that translate the color into
appropriate amounts of cyan, magent a, y el lo w, and black toner needed t o pro duce the desi red col or. The object
type information lets different color conversion tab les be used for different types of objects. For example, it is
possible to apply one type of color conversion table to text while applying a different color conversion table to
photographic images.

Should I use the P ostScript or PCL em ulation driver for the be st color? What driver set tings should I use
for the best color?

The PostScript drive r is strongly recommended f or best color quality. The default settings in the P ost Script driver
provide preferred color quality for the majority of printouts.

Why doesn't the printed color match

the color I see on the computer screen?

The color conversion tables used in Auto Color Correction mode generally approximate the colors of a
standard computer monitor. However, because of technology differences that exist between printers and
monitors, there are many colors that can be generated on a computer screen that cannot be physically
reproduced on a color laser printer . Color match can also be aff ected by monitor v ariations and lighting conditions .
See the response to the question “How can I match a particular color (such as a color in a corporate logo)?” on
page 6 for recommendations on how the printer Color Samples pages may be useful in solving certain
color-matching problems.

The printed page appears tinted. Can I slightly adjust the color?

Sometimes a user may consider printed pages to appear ti nted (f or exa mple, e v erything printed seems to be too
red). This can be cause d by envi ronmental conditions, paper type, lighti ng conditions, or us er preference . In these
instances, Color Balance may be used to create more preferable color. Color Balance provides the user with
the ability to make subtle adjustments to the amount of toner being used in each color plane. Select ing positive
(or negative) values for cyan, magenta, y ello w, and black under the Color Bala nce menu wi ll slight ly inc rease (or
decrease) the amount of toner used f or the chosen col or . F or e xample, if a user belie v es the ov era ll printed page
to be too red, then decreases to both magenta and yellow could potentially improve color preference.

Is it possible to increase the gloss in the printed output?

Obtain additional gloss by printing using the 1200 dpi Print Resolution Setting.

My color transparencies seem dark when projected. Is there anything I can do to improve the color?

This problem most commonly occurs when proj ecting transparencies with reflective overhead projectors. To
obtain the highest projected color quali ty, transmissive overhead proj ectors are recommended. If a reflective
projector must be used, then adjusting Toner Darkness settings to 1, 2, or 3 will lighten the transparency. Be
sure to print on the recommended type of color t ransparen cies. F or more inf ormation, see “Understanding pape r
and specialty media guidelines” in th e User’s Guide on the Software and Documentation CD.

Color Saver must be Off to adjust Toner Darkness.

What is Manual Color Correction?

The color conversion tables applied to each object on the printed page when using the default Auto Color
Correction setting generate preferred color for the majority of documents. Occasionally, a user may want to

apply a different col or tab le mapping. This customization i s accomplished using the Man ual Color men u and the
Manual Color Correction setting.

Manual Color Correction appl ies t he RGB a nd CMYK color con version table mappings as defined in th e Manual
Color menu. Users may select any of five different color conversion tables available for RGB objects
(sRGB Display, Display—True Black, sRGB Vivid, Off, and Vivid) and any of f our diff erent color conv ersion tab les
available for CMYK objects (US CMYK, Euro CMYK, Vivid CMYK, and Off).

Note: The Manual Color Correct ion setting is not useful if the s oftwar e applicatio n does not speci fy colors

with RGB or CMYK combinations, or in certain situations where the software application or the

Color quality guide

Page 6 of 7

computer operating system adjusts the colors specified in the application through color
management.

How can I match a particular color (such as a color in a corporate logo)?

Occasionally, users have a need for the printed color of a particular object to closely match a specific color. A
typical exampl e of thi s is when a u ser is trying to match t he color of a corporate lo go. While instances can occur
in which the printer cannot exactly reproduce the desired color, users should be able to identify adequate color
matches for the ma jority of cases. The Color Samples menu item can provide useful information in helping to
solve this particular type of color-matching problem.

The nine Color Samples values corres pond to color conversion tables in the printer. Selecting any of the Color
Samples values generates a multiple-page printout consisting of hundreds of colored boxes. Either a CMYK or
RGB combination is located on each bo x, depending on the table selected. The observed color of each box is
obtained by passing the CMYK or RGB combination labeled on the box through the selected color conversion
table.

The user can examine the color samples pages and identify the box whose color is the closes t to the desired
color. If the user finds a box whose color is close to the desired color match, but the user would like to scan the
colors in that area in more detail, then t he user can access the Detailed Color Samples by using the printer
Embedded Web Server interface, which is only available on network models.

The color combination labeled on the box can then be used for modifying the color of the object in a software
application. The software application Help section provides instructions for modifying the color of an object.
Manual Color Correction may be necessary to utilize the selected color conversion table for the particular
object.

Which Color Samples pages to use for a particular color-matching problem depends on the Color Correction
setting being used (A uto , Off , or Manu al), the typ e of object being printed (te xt, g raphics , or images), and ho w the
color of the object is specifie d in the softw are applicat ion (RGB or CMYK combinati ons). When the printer Color
Correction setting is set to Off , the color is based on the print job information; no color conversion is
implemented. The following table identifies which Color Samples pages to use.
